About Ottawa National Wildlife Refuge


​The Ottawa National Wildlife Refuge Complex lies on the southern shore of Lake Erie between the cities of Toledo and Port Clinton, Ohio. The complex consists of three refuges and two divisions. These refuges total approximately 11,000 acres and are managed by the U.S. Fish and Wildlife Service as part of the National Wildlife Refuge System.

The refuge has marshes, open water, wooded wetlands, coastal wetlands, shrublands, grasslands, cropland and an estuary. The complex provides a home for a wide variety of plant and animal species as well as a critical migratory bird resting area. The refuge staff strives to maintain a diversity of habitats to support the flora and fauna reminiscent of the area's early history.

You may have heard about "Vomit Island" from popular TV series Dirty Jobs.  Host Mike Rowe highlighted this protected area during a special trip with scientists to band herons. West Sister Island National Wildlife Refuge sits nine miles off shore of Ottawa National Wildlife Refuge in Lake Erie. President Franklin D. Roosevelt established West Sister Island in 1937 "as a refuge and breeding ground for migratory birds and other wildlife..." and it was specifically designated to protect the largest wading bird nesting colony on the U.S. Great Lakes. In January 1975, 77 acres of the 82 acre island were designated as a wilderness, part of the National Wilderness Preservation System. Access is by permit only.
